I had one in my R15 and it was great! Much MUCH better than the K&N Cone that made
the bike heat up and lose top end performance.

Re: Honda CBR 150 R

Hello guys! Few updates on my CBR...
I went into a huge pothole. noticed after 2 weeks that I was losing front tire pressure very frequently. On close examination, saw a bend on the rim. Here are the bent rim pics:

So I took it to SC, they recommended to claim insurance (ICICI). So I did, but it was rejected after the survey, as they said there weren't sufficient damages. So I asked them to repair it. The guy scared me by saying that there may be damages to the rim, and if thats the case then I have to pay Rs 6000-7000 to get a new one. After thinking a lot I decided to risk it and let them repair. Thankfully everything went fine, and the rim is as good as new. Although there were 2 small scratches on the opposite side. I was charged Rs 850 for that.
The whole process took 7 working days.

Also my coolant was leaking, and they replaced the pipe (it was torn) for free.

And also I replaced the tail lamp bulb myself. It costs Rs 25/- . I am thinking of getting LEDs from Ebay now.

Re: Honda CBR 150 R

Are the simota filters good?
How much of a difference will they make to the low end torque?

I've personally tried them on my R15 and the results were good! That's why I promote these filters.
Considering that the CBR150R has a closed-loop EFI system, the results should be even better.

Since these filters are free-er flowing than the stock filter, the engine breathes better. Hence, the difference
you will feel is better grunt in the low-end and faster revving of the engine.

Simota has designed individual filters for each model of bike, thats why you get a filter that fits snug
in your stock airbox with NO modifications (cutting, etc.) required.

No practical difference apart from sound!

See, all these filters do is make the engine breathe in more air (and dust) and correspondingly the FI system adjusts fuel flow to compensate for the extra air flowing in. This results in a growl from the air box and gives the feel of one going fast. But, in reality any after market filter (even if it is designed for your bike's model) causes harm in the long run.

In layman terms, consider your engine's life would be reduced to 70% of what it would have been as stock.

On SBKs, after market filters + aftermarket exhaust cans + ECU remapping + sprocketing helps them gain 10-12 bhp and roughly 5 Nm of torque. We are talking of a stock bike developing >150bhp here. What do you think a <20 bhp bike (all Indian bikes approx) would gain?

Stay stock. Save money and get a bigger bike.

I too had this kind of a confusion and if you can search in the Universal thread forum, you can see one, comparing k&n with that of Simota, . . So, the majority of the people said yes for K&N and no for Simota, saying that Simota is gonna kill the engine much faster than K&N and another of my friend who went ahead against my advice of not to go for Simota, suffered some problems when he used it for his 200NS, so better stick with K&N if you are going for air filters. . .

PS: Please stay out of those filters. . .

Cheers!!!

Contradicting lines!

Best bet is to stay stock. K&N fanboys would say they're best, same for UNI and Simota. Its an endless pointless debate on which of them harms the engine least, because at the end of the day, all of them would be killing the engine already!

Re: Honda CBR 150 R

Plz dont go for after market filters... They allow dust to pass through which is harmful for the engine in long run.. And although cbr has a closed loop, it cant adjust for this much change in air intake.. It has narrow band o2 sensor which can compensate only for very little change (like change in air intake due to unclean stock air filter)
So you'll be running lean with these aftermarket filters which is harmful for engine and thats the reason you lose top end and engine heating up. And you'll not gain acceleration.. Its because of the sound you feel that you have gained. The bike just revs a little bit faster and freely due to free intake.

Ps: why people are promoting here in xbhp?? Its not olx or quickr

Not always. I have posted this earlier and I'll do it again.

PGM-Fi operating logic also needs an explanation of what is called the 'open-loop' and 'closed-loop' operating mode for PGM-Fi. Closed-loop means a feedback-loop mode. PGM-Fi works in closed-loop mainly during engine idling. In closed-loop mode, PGM-Fi uses the signal from one critical sensor, the O2 (or sometimes known as lambda) sensor to attempt to attain an ideal air-fuel ratio of 14.7:1 (stoichometric ratio). An O2 sensor operates by measuring the amount of oxygen left in the exhaust gas. The amount of oxygen is a good indicator of the combustion efficiency and a higher oxygen content will suggest a lean condition and vice versa. O2 sensors are normally mounted on the exhaust manifold (or sometimes called the extractors) and/or catalytic converters (for cars equipped with them) and PGM-Fi uses the O2 sensor reading to bump air-fuel ratio up or down until it gets a reading indicating optimum combustion.

So during engine idling, the air-fuel ratio may initially fluctuate up and down based on O2 sensor readings but should eventually settle to a stable value corresponding to the ideal 14.7:1 ratio. PGM-Fi works in closed-loop mode only during idle or very light accelerator openings.

From moderate to maximum throttle openings, PGM-Fi goes into an open-loop mode. In open loop mode, PGM-Fi ignores the O2 sensor signal but will still use the other sensor signals (air temperature and pressure, TPS etc) to make compensations on the base injector opening values. However for very heavy accelerator positions (indicated by large TPS values), PGM-Fi now gives priority to engine RPM, MAP and TPS sensor readings. RPM and MAP sensors will always be required since they are input parameters for reading the fuel-map. But in open-loop mode, PGM-Fi no longer makes as much compensation for other sensor readings, other than TPS sensor, as in closed-loop mode.

When operating in open-loop then, PGM-Fi will usually be operating in a rich-mode. This will be especially true for JDM vehicles when imported directly from Japan into various countries (whether as used or new cars). The PGM-Fi program will have been originally designed based on the atmospheric conditions in Japan and they will almost certainly be different from the countries into which the cars are imported. Even for truly localized line-ups, a rich condition also normally prevail because the PGM-Fi program would have been originally developed to accomodate for the whole country or sometimes even an entire region and thus would again be based on a large base of 'average' values.

That's the reason I mentioned at the end, stay out of these

. . . I ain't a fanboy of either of the two, got some points, almost many don't know about Simota and Uni and after my friend saw the filtering quality of Simota, he's now cursing himself for going for that. . . Now, he's planning for some other filter (dumba**). . . Also, I had a forum started as mentioned above, so people who have used them and know something about each, said K&N is anyday better, he gave me a line of definition for both, what was that

. . ? Anyways as you say, better stay stock rather than spoil. . .

Cheers!!!

Even if they were any good, they will void the warranty, I am saying this for probably the 20th time, don't do anything that voids the engine's warranty.

There is no sound change due to these being the STOCK REPLACEMENT kind of filters. Due to better breathing
and the FI adjusting the fuel accordingly, there IS a perceptible difference in low-end torque. Obviously in quantifiable
terms the bhp/torque gain on paper is negligible.

Also, there is no harm to the engine as the Simota filters are not as free breathing as, say, a K&N. My R15 is running strong
even at 60,000km on odo. Switched to the Simota at 17,000km on odo.

Good for you bro that you feel your bike is still safe. I have seen many an R15s have their heads opened after running 35-40k on Simota filters. Plus, for barely some improvement I wouldn't want to compromise on the engine life.
